Initial Setup and Configuration

Battery Installation

Install two AA alkaline batteries into the battery compartment located behind the flip-down cover on the front of the thermostat unit. Ensure correct polarity. The thermostat requires batteries for operation and to retain settings during power outages.

Setting Time and Day

Upon initial power-up or after battery replacement, the thermostat will prompt you to set the current time and day of the week using the touch screen interface. Follow the on-screen instructions to accurately set these parameters.

Operating the Thermostat

Understanding the Display

Image: The main display of the LUX TX9000TS thermostat, illuminated with a blue backlight. It shows 'HEAT MODE', 'TUE DAY', current time '5:37', and room temperature '72°' with a flame icon, indicating heating is active. 'HOLD' is also displayed.

The large blue electroluminescent display clearly shows the current day, time, room temperature, and system status (e.g., HEAT MODE, COOL MODE, HOLD). Snowflake and flame icons indicate cooling or heating mode respectively. Audible touch confirmation indicates that your choices are being registered.

System Mode Selection

Use the physical switches located behind the flip-down cover to select the desired system mode: HEAT, OFF, or COOL.

Fan Operation

Use the physical switches located behind the flip-down cover to select the desired fan mode: ON (continuous operation) or AUTO (fan runs only when heating or cooling is active).

Temperature Adjustment

To temporarily adjust the temperature, simply touch the desired temperature on the screen and use the up/down arrows. This will initiate a temporary hold until the next programmed period.

Hold Function

The "HOLD" function allows you to maintain a specific temperature indefinitely, overriding the programmed schedule. To activate or deactivate, refer to the on-screen prompts or press the 'HOLD' button if available on your model's interface.

Programming the Schedule

The TX9000TS allows for seven-day programming, with up to four distinct time and temperature settings per day (Morning, Day, Evening, Night). You can set a different program for each day of the week to customize your home's heating and cooling schedule.

Programming Steps

1. Access the programming menu via the touch screen. The exact method may vary; typically, a 'Program' or 'Menu' button will be present.
2. Select the day of the week you wish to program.
3. Set the start time and desired temperature for each of the four periods (Morning, Day, Evening, Night).
4. Utilize the "COPY" function, if available, to duplicate settings from one day to another, simplifying the programming process.
5. Confirm your settings and exit the programming menu to save your schedule.

Default Energy-Saving Program

The thermostat comes pre-programmed with a default energy-conserving heating and cooling schedule. This schedule is designed to save up to $180 in energy costs over one year by optimizing temperature settings.

Maintenance

Battery Replacement

When the "REPLACE" icon appears on the display, it indicates that the batteries are low and need to be replaced. Replace with two fresh AA alkaline batteries promptly to avoid loss of settings and ensure continuous operation.

Filter Usage Monitor

The thermostat includes a filter usage monitor, allowing you to set limits from 0 to 720 hours of use. The display will indicate when it's time to check or replace your system's air filter, promoting efficient system operation and air quality.

Cleaning

Clean the thermostat's touch screen and exterior with a soft, slightly damp cloth. Avoid abrasive cleaners, solvents, or chemical sprays, as these can damage the display or casing.

Troubleshooting

Common Issues and Solutions

• No Display/Thermostat Unresponsive: Check battery installation and ensure fresh AA alkaline batteries are used. Verify power to the heating/cooling system is on at the main breaker.
• Incorrect Temperature Readings: Ensure the thermostat is not exposed to drafts, direct sunlight, or heat sources that could affect its internal sensor.
• System Not Responding to Settings: Check system mode (HEAT/COOL/OFF) and fan mode (ON/AUTO) switches. Verify wiring connections at the backplate. Ensure the 'HOLD' function is not active if you expect the programmed schedule to run.
• Programming Issues: Review programming steps carefully. If settings are lost, replace batteries and reprogram.

For persistent issues not resolved by these steps, consult a qualified HVAC technician.
